pseudoacacia L. between Durankulak village and
Durankulak Checkpoint.
The families with greatest number of genera and
species are as follows: Asteraceae, Рoaceae,
Rosaceae and Lamiaceae.
In the analysis of the biological types was
established pattern common to all habitats: most
numerous are perennial and annual herbaceous plants.
This confirms the results of research of Kozuharov et
all. [33].
In all habitats are most floristic elements with
circumboreal, European and Mediterranean origin.
The Tertiary relicts, which are established, are
trees and one shrub. They often have a secondary
origin for the habitats.
The species with protection statute in natural
habitats are most in Western Pontic Paeonian steppes
near to Bejanovo village – they are 8 species. In the
other habitats that number varies from 2 to 4 species.
In the forest shelter belts can be found a small
number of species with protection statute. Most often
they have gone from adjacent areas.
The number of anthropophytes in the natural
habitats is a significant – from 60.13% to 77.67%.
The reasons about this are mainly the following: the
strong fragmentation of natural habitats, arable land
in the vicinity – like source of anthropophytes,
improved access to the habitats and their accessibility
for people and domestic animals. In the forest shelter
belts the anthropophytes quite naturally are more –
from 73.86% to 87.50%.
